Reference sheet for the 2SA1300 transistor, supplied as a 207 KB PDF and filed under schematics in this index.

Small 81.5 KB PDF named after the 2SA1724 part number and filed under schematics. Nothing else in the name identifies a product or circuit board.

Small 20.5 KB PDF named for 2N5551 with a UTC tag, which most likely refers to the manufacturer that published this version.

Part code 1SV234 is the only detail in the name of this 65.8 KB PDF, which is filed as a schematic. No equipment model or board number is stated.

The part code 1SV229 is all this 69.4 KB schematic-category PDF carries in its name, apart from a trailing underscore. No equipment or board information is present.

Filed among schematics, this 61.3 KB PDF actually documents a single part, the JEDEC-registered 1N485B diode.

PDF datasheet of about 42 KB for the 1N4531, a small signal switching diode. The name carries no other details, so the vendor and document revision can only be read from…

Indexed as a schematic, the 180 KB PDF named 1G1-1G7 points to a numbered series of parts, most likely a rectifier diode family where the digits step through voltage…

Named simply 80SQ, this 125 KB PDF is indexed as a schematic, but the code looks like a series designation for a rectifier diode family rather than a circuit diagram…

PDF of 139 KB, listed as a schematic with the code 70epf02. The name carries no laptop model, board number or revision, so the subject must be confirmed by reading the…

A small 38.8 KB PDF titled 30WQ09F, catalogued among schematics but most plausibly a datasheet for a discrete rectifier, judging by the part-number style.

Compact 65.6 KB PDF stored as a schematic and labelled 28LV64A, part of the 28LV64 low-voltage EEPROM naming family, with the A suffix indicating a specific variant.

Listed among schematics, 30BQ015 is a 105 KB PDF whose name corresponds to a part-number pattern, so the pages are expected to be a component datasheet.

A 56.5 KB PDF from the Catalyst 24WC series, naming the 24WC32 and 24WC64, which are 32 Kbit and 64 Kbit two-wire serial EEPROMs; the schematic label aside, this is a…

An 85 KB PDF named 10BQ100, catalogued as a schematic but following the part numbering of a surface-mount Schottky diode family in the International Rectifier and Vishay…

Schematic for Sony motherboard MBX-147, supplied as a 1.25 MB PDF; no laptop model or revision is stated in the name.

Compal LA-D071P motherboard schematic in PDF form, 4.10 MB. The file name gives only the board number, so the laptop brand, model and revision are not stated here.

Portuguese-language PDF listing complete equivalences for SMD transistors, a cross-reference for identifying surface-mount parts by their marking code and finding…

Spanish course section 3.4 on the microscope, a brief 114 KB PDF from the workshop equipment chapter of a mobile repair series. No microscope brand or model is stated.
